“We are drowning in data, but starving for knowledge!” John Naisbett
Big data is defined as a large amount of data which continues to grow so much that it is difficult to manage and requires new technologies to store and analyse these data. Due to such enormous explosion of data it becomes difficult to manage data with the help of traditional techniques. This is a review paper which gives the basic introduction of big data, it properties, traditional data analysing technique like relational database management system (RDBMS) and Hadoop as the latest technology for analysing big data. The paper also includes the impact that Hadoop has upon business analytics.
